Abstract
The utility model relates to a surveyor which is used for plastic surgery of mitral valve, belonging to the technical field of medical equipment. The utility model is provided with a supporting rod (1), wherein, an asymmetric elliptical flat-plate (2) is arranged on one end of the supporting rod (1); a hole (4), a groove (3), and the groove (5) are arranged on the asymmetric elliptical flat-plate (2). When the utility model is used during an operation, the shape and the area of a prime physiological valve orifice can be measured, and a mitral valve molding ring which in proper size is selected orderly. An expanding and deformable valve ring can be folded directly in shape according to the shape and the size of the mitral valve molding ring through suture. Better effects of valve repair operation can be realized exactly and quickly.
Description
This utility model relates to technical field of medical instruments, is that a kind of mitral valvuloplasty that is exclusively used in the operation on heart is surveyed the lobe device.
At present, the mitral annulus enlargement deformation of the heart that the various causes of disease cause causes mitral incompetence, and then causes that cardiac failure is one of clinical common heart disease.The annulus of mitral valve of pathological changes enlargement deformation is corrected to the normal physiological state recovering the plastic surgery for mitral valve of valvular function,, is better than valvular prosthetic replacement's art improving patient more aspect back and the postoperative life quality.But the difficulty on the surgical technic is bigger, and particularly the mitral orifice measurement is slower in the operation, and is difficult to accurately, thereby brings many inconvenience to patient and operation technique person, is difficult for reaching promising result.
The purpose of this utility model is, a kind of mitral valvuloplasty valve gage is provided, in operation, play the rule effect, after making surgical doctor in operation, carry out bigness scale earlier, can compare the lobe ring portion position, lesion degree and the former physiology lobe mouth size that estimate pathological changes rapidly accurately, in view of the above, select the suitably mitral valvuloplasty ring of size, or directly successively the annulus of mitral valve of enlargement deformation is stitched and shorten shape into, make valve repair reach effect preferably accurately, rapidly.
The technical solution of the utility model is, valve gage has a pole (1), and an end of pole (1) is installed asymmetric elliptical flat-plate (2), has hole (4) and groove (3), groove (5) on the asymmetric elliptical flat-plate (2).The two ends of pole (1) also can be installed asymmetric elliptical flat-plate (2) respectively, and the size of the distance L between groove (3) and the groove (5) is respectively 24mm, 26mm, 28mm, 30mm, 32mm and 34mm.
Description of drawings: accompanying drawing 1 is this utility model structural representation; Accompanying drawing 2 is that accompanying drawing 1A is to view.
The contrast accompanying drawing elaborates to embodiment of the present utility model:
(1) is the pole of adopting metal material to manufacture among the figure, and asymmetric elliptical flat-plate (2) is installed at the two ends of pole (1) respectively, has hole (4) on the asymmetric elliptical flat-plate (2), and pole (1) is installed in this hole.Have two upper grooves (3) and groove (5) on the asymmetric elliptical flat-plate, the distance L between two grooves is 24mm.The concrete manufactured size of asymmetric elliptical flat-plate (2) is h '=55mm, h=19mm, d=28mm.This utility model can be made into various series, to be used for different patients, alleged different series, it mainly is the variation of the various sizes in the asymmetric elliptical flat-plate (2), for example: the mitral valvuloplasty valve gage of another model, its size are respectively L=26mm, h '=6mm, h=21mm, d=30.7mm.
This utility model can be surveyed the shape and the area of the former physiology lobe of patient mouth in operation, select the suitably mitral valvuloplasty ring of size successively, or directly with suture the lobe ring of enlargement deformation is contracted with these shape and size and to be converted into shape.Can correct mitral incompetence preferably like this, can guarantee the area of effective lobe mouth physiological need again, make valve repair reach better effects accurately, rapidly.
Claims (2)
1, mitral valvuloplasty valve gage, it has pole (1), it is characterized in that: an end of pole (1) is installed asymmetric elliptical flat-plate (2), has hole (4) and groove (3), groove (5) on the asymmetric elliptical flat-plate (2).
2, according to the described mitral valvuloplasty valve gage of claim 1, it is characterized in that: the two ends of pole (1) can be installed asymmetric elliptical flat-plate (2) respectively.
